checked the fork legs. they are fine. front tire is really choppy on the sides thow. still havnt put the new one on. im pretty sure the fork oil needs to be changed or its low also. ill check all my bearings tonight when i get out of work. im pretty sure its just the difference between the 2 bikes.

bit of an update. checked the air level in the forks. it was empty. pumped it up to 30ish. and its still holding air. front end feels a lot lot better. also adjusted the katana clipons to where i like them. turn signals are working... msot of the time. started messing around with paint ideas. i dont know about this one. haha. i like it but eh. spend a little time cleaning... a very little time. i must have routed my throttle cable wrong thow. i crimped it on my stearing lock. oops. i have the one off the 850 thats almost new. thats it for now. opinions on the paint? be gentle please lol.
 
Let's see how many times I can mess up today. Got my wires. Caps. And clutch springs in the mail today. Epoxied the plug wires in and put the caps on. Put the coils on. I put the caps for 2 and 3 on the wires for 1 and 4. Switched them. Tried to start her and she just cranks and cranks. Make sure there was fuel. Then noticed that the inputs for the coils wernt plugged in. Plugged them in. Cranked her. All the would do is backfire. Switched the inputs and she fires right up. Runs great for about 10 seconds then starts sputtering and spitting then dies. Find out its only running on 2. Check the coils. The epoxy came un done. It was all melted and gooy. Looked at the bottle I used and it wasn't epoxie it was clear flexible water sealer. Awesome. This time I used a putty like jb weld. Then put electrical tape around it. Then a hose clamp so it wouldn't move while it was curing. Hooked it all back up and she fired and idled perfectly. Took her for a ride and she rides suprisingly good. I think I'm going to try raising the needle a notch and maybe bumping the mails up a size or 2. But she runs amazingly well
 
thats gotta be it. im really excited. i wish i had a before pic and had actually listed everything i did to it. it was little more than a frame and a box of parts when i got it.
 
rode the bike to work today, clutch slipped a bit now and then, has new clutch springs in her. but i noticed the clutcj cable was a tad tight. adjusted the throttle cable after i got here so hopefully that reduces the low speed jerking. also the bike rides really well above 10ish mph. below that its a bit squirly. i gotta back the air screws out a half turn or so and raise the needle a notch, that may be it. but probably not
 
just me or do you need a new front tire?, thats dangerous my friend,be careful dont want anything happening to you or anyone on back , there real cheap compaired to a crash, -just trying to help a fellow rider:)
will that exhaust get the rear tire to hot?
 
i have the 83 750 ed and it rode like crap with no air in the forks , i added a couple pounds like the manual said not more ,and its like a different bike, dont blow your seals
i think a heavy set of springs will really help, all the weigh it pushing on it
im a big guy, so the air is def a help
 
i have a new front tire. just havnt had time to take it to get put on. and the exhaust doesnt come anywhere near the rear tire, it points to the right
unfortunatly the clutch is slipping badly even after new springs. grrr. i also raised the needle one notch and backed the air screws out half a turn and still seems to have a bad spot
 
hm. the clutch for the 750 and 850 are the same part number. sould it be a bad idea to take all the plate from the 2 bikes and pick out the best of them, scuff them up, and put it all back together? also. what can i do to make the springs snap stronger? if i added some preload by using a few washers would that change anything? also, what about adding an extra clutch plate and steel plate? thanks guys. i would never have gotten this thing running without your help.
 
if you add washers, i would just get performance springs, but if you do , make sure they dont bind up on ya
check the basket for "chatter marks" "grooves wore into the tabs"
the plates get stuck in them
 
the clutch is extremely smooth, no binding. just slips a bit under full throttle. adjusted the carbs a bit. runs a good bit better. has a really small stutter that is barely noticable. its only there when the rpms are low. lower than i usually run them. im gonna rip the clutch apart on the 750 and 850, take the best steels and fiber plates, scuff up the steels, maybe add a really thin washer or spacer to the springs. havnt decided yet.
 
also. the only gauge on the bike that works is the speedo. should i just take the whole cluster off and get a small speedo?
 
Did you go stock on the springs?
Do you have a manual and a caliper? I'd spec the fibers and steels before installing them.
Do you have the wave washer installed properly behind the piano wire at the back of the clutch pack?
I fought clutch slippage until I used some HD springs.
 
new stock replacement springs. and as far as i know the thing hasnt been apart. but ill find out the rest tonight when i take her apart
 
rebuilt the clutch today. all the steels were blued and smooth. rouched them up. clutch material looked brand new thow. put it all back together, new stock springs with a 16th of an inch washer that fits inside the spring hole and around the post in there and it is like a whole new machine. wot and power shifting and she just bites harder and harder. then a coil died on me. bugger. threw a coil from the 850 on her thow and shes running like a champ now. i was gonna get new coils when i could afford them anyways. installed my turn signals, and painted her all gloss black. the patina look wasnt working for me. ill post pics of her within the hour.
next on the list:
put the new front tire on
new braded brake lines
new pads
new chain
new sprockets
new grips
um. thats all i can think of for now.
